Commit e05e5de7fae5bec79617e113916dac6631251156 made ARM's relocate_code() return to its caller, but it did not update its declaration accordingly.

Fixing this function declaration fixes dropped C code following calls to relocate_code().

The purpose of .globl is to export symbols for ld, not to declare external symbols.

By the way, use the ENTRY() and ENDPROC() macros to define functions rather than using .global directly.

Change CONFIG_SPL_PAD_TO from a link address to an image offset since this is more handy and closer to the purpose of this config.

Automatically define CONFIG_SPL_PAD_TO to CONFIG_SPL_MAX_SIZE (or 0 without CONFIG_SPL_MAX_SIZE).

Test that CONFIG_SPL_PAD_TO >= CONFIG_SPL_MAX_SIZE if CONFIG_SPL_PAD_TO is non-zero.

This also fixes support for mx31pdk and tx25, which had been broken by commit e05e5de7fae5bec79617e113916dac6631251156.

Signed-off-by: Benoît Thébaudeau benoit.thebaudeau@advansee.com Tested-by: Fabio Estevam fabio.estevam@freescale.com --- Changes in v8: - Update doc/README.arm-relocation. - Drop useless line feed at end of inline asm. - Set CONFIG_SYS_NAND_U_BOOT_OFFS to CONFIG_SPL_PAD_TO instead of CONFIG_SPL_MAX_SIZE (this is a cosmetic change since they now have the same value). - Enlarge CONFIG_SYS_NAND_U_BOOT_SIZE from 0x30000 to 0x32000 to let u-boot.bin fit in.

Changes in v7: None Changes in v6: - Automate 'u-boot.imx' and 'SPL' make targets for all imx processors. - Move board_init_f() to <board>.c. - Get rid of board SPL linker scripts. - Define CONFIG_SYS_NAND_U_BOOT_OFFS as CONFIG_SPL_MAX_SIZE rather than duplicating the constant value. - Define CONFIG_SYS_NAND_U_BOOT_DST as CONFIG_SYS_TEXT_BASE rather than duplicating the constant value. - Pass 0 as the 1st argument to relocate_code() since it's unused. - Fix stack pointers. - Rebase on latest u-boot-imx/master. - Move unrelated changes to separate patches.

Changes in v5: - Remove spaces between function name and open parenthesis. - Fix mx31pdk and tx25 Makefile-s and SPL linker scripts. - Remove the useless definition of CONFIG_SPL_LDSCRIPT. - Fix the call to nand_boot().

Changes in v4: - New patch.

-Relocation with NAND_SPL (example for the tx25): +Relocation with SPL (example for the tx25 booting from NAND Flash):

- cpu copies the first page from NAND to 0xbb000000 (IMX_NFC_BASE) and start with code execution on this address.

-- The First page contains u-boot code from u-boot:nand_spl/nand_boot_fsl_nfc.c - which inits the dram, cpu registers, reloacte itself to CONFIG_SYS_TEXT_BASE and loads +- The First page contains u-boot code from drivers/mtd/nand/mxc_nand_spl.c + which inits the dram, cpu registers, reloacte itself to CONFIG_SPL_TEXT_BASE and loads the "real" u-boot to CONFIG_SYS_NAND_U_BOOT_DST and starts execution @CONFIG_SYS_NAND_U_BOOT_START

- This u-boot does no RAM init, nor CPU register setup. Just look where it has to copy and relocate itself to this address. If relocate address = CONFIG_SYS_TEXT_BASE (not the same, as the - CONFIG_SYS_TEXT_BASE from the nand_spl code), then there is no need + CONFIG_SPL_TEXT_BASE from the spl code), then there is no need to copy, just go on with bss clear and jump to board_init_r.

This image combines the SPL with the i.MX header and U-Boot. This is a convenient way of having a single image to program on some boot devices.

The i.MX header has to be added to the SPL before appending U-Boot, so that the boot ROM loads only the SPL.

Signed-off-by: Benoît Thébaudeau benoit.thebaudeau@advansee.com --- Changes in v8: - Use CONFIG_SPL_PAD_TO instead of CONFIG_SPL_MAX_SIZE for padding, which allows to pad the SPL after adding the i.MX header, which may save time when the boot ROM loads the SPL. - Add /u-boot-with-spl.imx to .gitignore.

Changes in v7: - New patch.

The migration of boards from Makefile to boards.cfg was due for v2012.03, but smdk6400 did not follow, and it does not build, so move it to scrapyard. It will still be possible to restore it from the Git history before fixing it.

Following the removal of the smdk6400 board, the MMU setup code in arm1176/start.S becomes unused, so move it to scrapyard. It will still be possible to restore it later from the Git history if necessary, in which case it should be moved out from the relocate_code() function.

Factorize start.S code as much as possible.

Functions that may need to be customized for some start.S are defined weak for that purpose.

relocate_code_prepare() and relocate_code_finish() are introduced as hooks to be executed at the beginning and at the end of relocate_code() if needed by some start.S, e.g. for special cache or MMU operations.

Hi Fabio,

From: Fabio Estevam fabio.estevam@freescale.com

Introduce CONFIG_SYS_NAND_BUSWIDTH_16BIT option so that other NAND controller drivers could use it when a 16-bit NAND is deployed.

drivers/mtd/nand/ndfc has CONFIG_SYS_NDFC_16BIT, so just rename it, so that other NAND drivers could reuse the same symbol.

FYI, I've just fixed a space damage (space before tab warning) here when applying.
